i vented a new and Improved Refrigerator, of

which the following is a full, clear, and exact description. i l i This invention relates to certain improvements in cooling devices, and more particu'- larly to a refrigerator adapted to be cooled by a cooling liquid rather than by the elnployment of ice, the construction being such that the liquid is distributed over an evaporating surface and air is caused to circulate over the surface to evaporate a portion of the water and thus lower its temperature.

One special object of the invention is to utilize the current of water delivered to the evaporating surface for operating the fan which causes the circulation of air.

Reference is to be had to the accompany ing drawings, forming a part of this speciiication, in which similar characters of reference indicate corresponding parts' in both the figures, and in which- Figure 1 is a vertical section through a refrigerator constructed in Vaccordance with my invention said section 'being taken on the line 1 1 of Fig. 2; and'Fig. 2 is a hori zontal section on the line 2 2 of Fig. 1.

r1`he specific embodiment of my invention which I have illustrated in the accompanying drawings involves a rectangular casing provided with shelves and resembling in appearance an ordinary refrigerator, although it=is evident that the principle employed may be utilized in various other forms and constructions.

In the construction illustrated there is provided a storage chamber for the reception of the articles to be cooled, and this chamber is preferably formed by substantially verti` cal walls 10 and .a top wall 11. Any suitable form of shelves 12 may, if desired, be supported within the chamber. The walls are preferably of enameled metal and form three sides of the chamber. Inclosing the chamber and spacedtherefrom is any suitable form of insulating 'wall 13, which wall is connected to the inner walls 10 at the front.

tutes an evaporating space and through this space air is caused to circulate to facilitate the evaporation of water `iiowing over the outer surface of the innen walls. For delivering the water and creating the air circulation, I preferably provide an opening 15 in the top of the outer casing, and substantially equi-distant from the side walls; and within the opening is disposed a suitable fan 16. center of the iiat top and mounting tle fan within this opening, the fan is equi-distant from all sides of the refrigerator and creates anequal 'circulation of air through the eva'porating spaces at each of the sides.

Directly beneath the fan there is provided a water wheel 17 operatively connected to said fan and adapted to be rotated by a cui and escaping through a conduit 19. The iirst-mentioned conduit leads from any suitable source ofwater under pressure and the last-mentioned conduit leads to a spray pipe 20 extending across the rear of the rel frigerator and along the two opposite sides adjacent the upperV edge of the inner walls 10 The casing of the water wheel and the pipes 18 and 19 leading to and from the same, are in direct contact with the top wall 11 of the provision compartment. The warmest air in. the compartment will be in engagement with the under surface of the lwall 11 and if this air be warmer than the water delivered through thewater motor, the air will be cooled by direct conduction of the heat through said wall 11 to the water before the latter is evaporated. The; spray pipe is provided with openings so disposed that the water escaping therefrom will be directed against the outer surface of said walls and tlow-thereover to the lower por tion iof the refrigerator. The water entering the conduit 18 operates the wheel and is then delivered to the spray pipe. The operation ofthe water wh'eel causes the rotation of the fan, which latter forces a current ofv air through the evapo'rating space to v'evaporate the water flowing over `the walls. The. excessof waterrnotevaporated is collected in angr suitable form,l of trough 21 at the lower portion of the evaporating space and may escape through a suitable waste conduit 22. The air after passing over the linoistened surface may escape through suit1 able apertures 23 at the lower portion of the outer easing. It willtthus be noted that the rent of water entering through a conduit 18 By disposing the opening 15 in the and" by positioning the fan in the center of claim asl new and desire to secure by ALetters Patenti .posed opening therethrough substantially topi space and adjacent the opening'in the ingl water from said water-wheel to said per portion of the refrigerator by conducfrom all sides.

'walls forming an evaporating space therewater 'serves a triple function, in that it operates the fan, removes heat from the uption, and evaporates in evaporating spaces to cool the side walls of the provision compartment.-4 The fan serves to create a circulation of air through the evaporating spaces,

thetop, it draws eq-ual quantities of air ,Having .thus described my invention, I
